RECIPBOCATING ICE-CUTTING MACHINE.

Specification of Letters Patent.

Application filed September 8, 1915. Serial No. 19,560.

To all whom it may concern:

Be it known that 1, CHARLES E. LEADER, a citizen of the United States, residing at Madison, in the county of Madison and State of New York, have invented certain new and useful Improvements in Reciprocating Toe-Cutting Machines, of which the following is a specification.

This invention relates to an improved ice cutting machine of the type in which the saw is mounted for reciprocating movement and the principal object of the invention is to provide an improved type of carriage or sledge and to provide an improved means for mounting the saw blade for vertical reciproeating movement.

Another object of the invention is to so mount the saw blade as to permit it to be swung upwardly out of the way when not in use.

Another object of the invention is to provide an improved guiding means for direct ing the movement of the carriage across the ice, the guiding means being adjustable according to the width of the block of ice it is desired to out.

Another object of the invention is to provide a sawing machine which will be very strong and durable but which at the same time will be comparatively simple in construction.

This invention is illustrated in the accompanying drawings, wherein Figure 1 is a view showing the improved ice cutting machine in side elevation, Fig. 2 is a view showing the improved ice cutting machine in end elevation. Fig. 3 is a fragmentary view taken along the line 3-3 of Fig. 2 and looking in the direction of the arrow.

The sledge which may be termed a carriage is provided with the side bars or runners 10 which carry the platform or head 11 upon which the engine 12 is mounted. This represents a conventional type of engine and therefore is not illustrated in detail. A pulley wheel 13 is mounted upon the shaft 14 of the engine so that power can be transmitted from the engine to the crank shaft 15 through the medium of the driving belt 16 which passes around the pulley wheel 17 carried by the crank shaft 15.

In order to slidably mount the block 18 there are provided the standards 19 and 20 which extend upwardly from the runners of the carriage in spaced relation upon opposite sides of the block. The upper ends of these standards are connected with the cars 21 of the cover plate 22 which cover plate serves as means for bracing the standards as well as serving as a protector for the crank shaft 15 which crank shaft is rotatably mounted in the bearings 23 carried by the bars 24. The bars 2 1 in addition to serving as means for supporting the bearings 23, serve as additional means for bracing the standards against spreading action and therefore the standards will be securely held in the vertical position and cannot move to allow the block too much play or cause a binding action against the block. A binding 25 is placed around each end of the block and bindings 26 are placed against the faces of the standards so that wherein action caused by frictional engagement between the standards and block will be reduced.

The saw 27.is secured to the bracket 28 by means of rivets or other fasteners 29, the

bracket being carried by the cross bar 30 which in its turn is connected with the head 31 by means of the hinged ears 32. This head 31 extends transversely of the neck 33 leading from the block 18 and it will thus be seen that a very strong and rigid structure is provided. for slidably mounting the saw.

It will be further noted that when the saw is not in use the cross bar 30 may be swung upwardly to rest upon the head 31. It will be further noted that in order to securely connect the neck 33 with the block 18 there has been provided brackets or cleats 34: shown in Fig. 3.

Then this device is in use the saw will be in the position shown in Fig. 1 and as the crank shaft 15 rotates the draw bar or shaft 35 which is rotatably mounted upon the crank shaft and connected with the bracket 36 by means of bolts or other fasteners 37 will be reciprocated thus giving the block a vertical sliding motion which will reciprocate the saw and cause it to cut through the ice. Of course, horses or some other draft means will be connected with the shaft 38 of the sledge so that the sledge will be drawn across the ice as the ice is cut by means of the saw. After the first cut is made the sledge will be drawn across the ice parallel to the first cut with one of the blades or guiding fingers 39 fitting into the out already made. These guiding fingers or blades are slidably and rotatably mounted upon the shaft 40 and are held in an adjusted position upon the shaft by means of the set screws 41. Therefore a selected one of the guiding plates or fingers can be held in the opposite position as shown in Fig. 1 to extend into the out already formed in the ice and the second guiding finger can be swung to rest upon its supporting bracket 42. It should also be noted that by sliding the fingers along the shaft the widthof the strip of ice cut can be regulated. When it is no longer desired to use the machine or' when removing the machine from a finished cut to a place where a new cut is to be made the saw blade 27 can be swung upwardly out of the way and the machine then drawn across the ice.

I have thus provided a machine for cutting ice which will be very strong and durable and very efficient in use and which will be very simple in construction.

l/Vhat is claimed is 1. A sawing machine comprising a car copies of this patent may be obtained for mounted in said guide way, a neck extending from said block, a head at the outer end with said head for vertical movement, a cutting implement connected with said cross bar and means for moving said block in the guide way with a vertical reciprocating movement.

3. An ice cutting machine comprising a carriage, standards carried by said carriage and constituting a guide way, a carrying elcment slidable in said guide way, a cross bar pivotally connected with said carrying element, a cutting element connected with said cross bar, and means for moving said carrying element in said guide way.

4. An ice cutting machine comprising a carriage, standards carried by said carriage in spaced relation to provide a guide-way, a block slidably mounted in said guide-way and provided with a neck extending beyond the end of said carriage and provided with a head extending transversely of said carriage, a cross bar hingedly connected with said head. for vertical swinging movement into and out of an operative position, a cutting medium connected with said cross bar, and means for reciprocating said block in said guide-Way.

In testimony whereof I aflix my signature in presence of two witnesses.
